To all whom t may concern:

Be it known that l, FOSTER MILLrnEN, a citizen of the United States, and a resident of Lawrence, in the county voiNassau and State of New York, have invented a new and ll'mproved Street-Light, of which the following is a full, clear, and exact description.

This invention relates to street lightsv and has for an object the provision oi an improved construction, which may be used on the street at any place and acts in the double capacity of a 11g ting device and signal device.

Another object of the invention is to ron vide a street signal light which will pro uce v flashes of light intermittently and thereby attracting the attention or persons passing the li ht.

A 'urther object of the invention is to` provide an easily movable street light adapted to be placed at any point, as for instance, cross-roads in the country or crossstreets in towns, and by reason of its construction present proper signs for guiding pedestrians and vehicles and at the same time 've intermittent concentrated dashes of lig t. v

lin the accompanying drawings:

Figure l is aside View of a street lamp embodying the invention.

, Fig. 2 1s a longitudinal vertical section through the lamp shown in Fi l, same being taken approximatelg; on t e line 2-2 of Fig. 3. y A

Fig. 3 is a transverse sectional view through Fig. 2 on line 3-3.

Fig. A is a sectional view' similar to Fig. 3, as shown in a slightly modied form of the invention.

Fig. 5 is a sectional view similar to Fig., 4 disclosing a further modified form oit the invention.

Fig. 6 is a sectional view similar to Fi s. 4 and 5, but disclosing a still further slight y modiiied form of the invention. y

Fig. 7 is a side view of the upper part of a street lamp embodying the invention, certain parts being broken away for. illustrating the construction, Isame illustrating a modified form of motor to that shown in Fi 2. Fig. 8 is a view similar to Fig. 7, but disclosing -a further modified lamp arrangement and motor when electricity is utilized.

Referring to the accompanying drawing 1 by numerals, ll indicates a base to which a terial, as for instance, metal, and pressed so as to produce an ornamental construction as shown in Fig. 3, though other shapes may be used without departing 'from the spirit of the invention. Whenthe casing is made square, a glass panel 5 is arranged in each side, each of the panels being provided with a pair of lenses 6 and 7 preferably con-1 nected to the glass panels, though separate lenses could be provided if desired. The

lenses 6 and 7 are spaced apart the same distance as the lamps 8 and 9 so that when the lamps are in the position shown in Fig. 2 a concentrated or very brilliant light will be projected through the lenses 6 andy7., which preferably are red for indicating danger andl attractmg the attention of persons passing. For the sake of cheapness in construction the various panels or panes 5 may be flat sheets of glass, ground glass being preferable, while the lenses 6 and 7 may be separate members secured in any suitable manner to the panes 5 or supported adjacent said panes, substantially as shown in Fig. l. Arranged in theicasing 4 (Fig. 2) are oil burning lam s 8 and 9 provided with a common tan 10, though an independent tank could be provided if desired. llt will also be evident that other forms of lamps maybe used, as for instance, electric lamps, as hereinafter fully described.v A double faced reflector 11 is preferably arranged between the lamps so that when they are turned in a position at right angles to that shown in Fig 2-there will beno shadow cast by one vlamp on the other, whereby proper illumination of the entire casing is provided in addition to producing comparatively dull red sections caused by the lenses 6 and 7, which lenses may be. red in themselves or may have coloring matter connected therewith, or arranged so that the rays of light passing through the lenses will pass through the coloring matter. The tank or container 10 shown in Fig. 2, is mounted on a suitable turn-table 1 2 connected inainr suitable manner with a motor 13 or' any desired type, as for instance, a spring motor, 1

though an electric or weight motor could be used without departing from the spirit ofthe invention. rlhis motor is Vpreferably made of a size to run continuously for ten or twelve hours, though afstronger or weaker motor may be used if preferred. The intention is to start the motor going-at dusk and to regulate the motor so that the lamps 8 and 9 will turn slowlyall night whereby there will 'be a bright `Hash of red light whenever the respective lamps are directly in line with the lenses 6 and 7. 1t will be 4observed that the red light will be flashed A8 and 9 are inclosed in the casing 4 vso` the wind, rain andthe like cannot effect the same, openings 15 being provided at the' top for ventilation, while suitable openings 16 and 17 are provided vat the bottom where air enters to cause a proper combustion. Ity

will be notedthat the lamps produce an illumination of the street surface in addition to producing the iashes of red light. The v'arious panes of glass 5 are provided with signs of any suitable kind, as for instance,

the name of the street and an order, as for instance, Keep right, as illustrated in Fig. 1. One of the panes 5 is mounted in. a door frame 18 which is supported by suitable hinges 19 and held normally closed by a catch 20. This permits ready access to the lamps while not in any way disturbing or changing the appearance of the completelight. r1`he lenses 6 and 7 are spaced a short distance apart, namely the same distance as the lamps 8 and 9 and are in horizontal line substantially centrally of the pane of glass, but it is evident that these lenses could be 4differently arranged if desired. Toaugment or to make more eective the illumination of the street by the lamps 8 and 9 the interior surface 21 of the casing is made from some brightv material, and if desired may be supplied with reflectors.

Referring particularly to Fig. 4, it will be seen that on opposite sides of each of vthe -lamps 8 and 9 are arranged lenses 22 and 23, said lenses being supported upon the container 10, although they may be supported in a suitable manner on the interior withoutdeparting from the spirit of the invention. Arranged on each ofthepanes of glass 5 are sections 24 of red matter which may be painted on to the glass,

7 formed in the glass, or applied in any desired manner so as to produce a, section recente through which the concentrated rays from the lenses 22 and 23 will pass for producing concentrated rays of red light at certain intervals as the lamps move. 1n addition to producing intervals of bright red sections on the panes of glass 5, lenses 22 and 23 will produce continuous concentrated rays moving in a circle so that in addition to the general illumination produced by the lamps 8 and 9, these streams of concentrated rays of light will give the device a distinctive character which will compel the attention of any passing the device. It will thus be seen in this form of the invention the same flashes of intermittent red light will he produced and in addition rays vof concentrated light will be produced moving in a circle.

1n F ig.'5 a further modified form of the invention is disclosed wherein the container l 10 carries reflectors 25 and 26, while the panes 5 carry lenses 6 and 7 in a similar manner to that shown in Figs. 1 and 3, but these lenses may either be colored or may have coloring matter adjacent thereto, so that all rays of light passing therethrough will be colored, as for instance red. As the lamps 8 and 9 move in a circle there will be produced an intermittent or winking light on the dierent sides of the casing 4. When the parts are arranged as shown in Fig. 5 a concentrated raf,T of red light will be projected through one lens in one face of the `device, and a concentrated ray of red light projected through another lens in the opposite face of the device and at substantially the opposite corner.

In Fig. 6 a further modified form of the invention is shown in which the lenses 6 and 7 are arranged on the chimneys 27 and .28, which chimneys are preferably frosted or ground. rlhe lenses in this instance may be made separate and connected to the chimneys, or made integral with the chimneys and either colored or uncolored. llit the lenses are not colored coloring matter 29-is arranged at different points on the 'panes 5 so as `to produce substantially the same effect as produced for instance in the form shown in Fig. 1.

As heretofore stated a spring motor 13 is provided for rotating the table 12 in the preferred form, but it is evident that any other desired motor could be used without departing from\the spirit of the invention, asvfor instance 'a weight motor 30 can be provided as shown in Fig. 7, the-weight 31 extending into the hollow standard 2. Whenever desired electric current could be used and the lead-in wires 32 and 33 may pass up through the hollow post 2, connected at binding post 34 tothe electric motor 35 and at 36 to brushes which connect with the slip rings 37 and 38, said slip rings being connected in turn with the filaments of lamps 39 and 40.'
